UNITED STATES PATENT OFFICE.

GEORGE IY. HARRIS, OF MOUNT ZION, ILLINOIS.

HEATER.

SPECIFICATION forming part of Letters Patent No. 461,017, dated October13, 1891.

Application tiled February 26, 1891- Serial No. 382,990- (No model.)

To @ZZ whom it may concern.-

Be it known that I, GEORGE V. HARRIS, of Mount Zion, in the county ofMacon and State of Illinois, have invented certain new and usefulImprovements in Heaters, otwhich the following is a specification.

This invention is designed to form a part of a stove in which anthraciteorbitu minous coal is burned; but it may also be used in conjunctionwith a Vapor-burner or with other fuel.

The object is to increase the eiiiciency of the fuel by exposing a largeheating-surface; and the invention consistsin the construction of theheating-drum and in the devices used to clean the tlues of the same, aswill hereinafter appear from the detailed description and claims.

In the drawings accompanying and forming a part of this specification,Figure 1 is a representation of a stove embodying my invention. Fig. 2shows theheater detached. Fig. 3 is a cross-section on broken line X inFig. 2. Fig. 4 shows a tube-cleaner. Fig. 5 is an enlarged centralvertical section ot Fig. 2.

A set of tubes l is arranged concentrically around a drum 5, and bothtubes and drum are open at their ends and connect at their upper endswith head-cavity 2 and at their lower ends with the tire-pot. A door isshown at 3. rlhe fuel-pot is seen at 4. In Fig. 5 a magazine is shown at6.

The tube-cleaners consist each of parallel bars 7, adapted to the innercircumference of the tubes, a head 9, which closes the tube opening andby means of which the cleaner is turned in the tube, and a ring 8, towhich the ends of the parallel bars are secured. The bars are formed oi'one piece bent at its center and secured by a bolt to head 9.

The heating-drum is to be placed over the fire -pot, and the heat passesthrough the tubes and the drum to the head 2, from which the products ofcombustion, as carbonio oxides and acids, pass through the fine.

As a result of the construction of the heater a great amount of surfaceis exposed, so using the fuel advantageouslyand economically, and at thesame time an attractive design may be easily produced.-

In case of the use of bituminous coal, the magazine may be omitted, andwith other fuels and under other circumstances the form of the heatermay be varied.

The cleaners do not interfere with the usefulness of the tubes, and whenit becomes necessary the tubes may be cleaned of soot, tbc., by turningthe bars around or by raising` the ring up andr down, the head 9 beingshaped to readily permit such operation.

The number of the tubes or the manner of connecting them with the headand base may 4be Varied without affecting the principle of my invention,which consists inl. The combination of drum 5, tubes l, head 2, and tubecleaners composed of bars 7, rings 8, and heads 9, as set forth.

2. Atube-cleaner for tubes of heaters, comprising bars 7, formed of asingle bar bent at the center, head 9, to which the bars are bolted, andring S, secured to the ends of the bars, as set forth.

In testimony whereof I sign my name in the presence of two subscribingWitnesses.
